`init_from is deprecated` warnings on create collection calls about qdrant-client

[joein]

Hi @viktorku

We've indeed deprecated InitFrom functionality, since it might not work correctly if there are ongoing write operations in the source collection
Hence the warning

Thanks for the clarification @joein. Does it make sense to have a warning that communicates that? I'm currently using it only for migrations during downtime, and no ongoing operations will obstruct the "copy" process.

If the plan is to ultimately remove the init_from functionality altogether, then I'd have to resort to calling the API directly. But it wouldn't make sense to remove it from the client if the service still supports it...
